After the Nobel Prize was given to the inventors of the blue LED, I wrote a post making the case that the use of LEDs would not lead to a huge reduction in electricity use, because inventors and designers would keep dreaming up wonderful (or not so wonderful) uses for them. From billboards to public toilets, LEDs are consuming milliamps in ways that nobody anticipated. I even mentioned Jacob Sutton's LED covered snowsuit. Now, if you need more evidence of the rebound effect, or Jevons' Paradox, here's a skier in an Philips LED suit doing a run.
For those who missed it, here is William Hughes, filmed by Jacob Sutton a few years back:
Filmed as a partnership between Sweetgrass Productions, Philips TV, and the Swedish Agency Ahlstrand & Wållgren, it's two parts creativity, one part branded content, and a pinch of masochism for good measure. Overall, it's an incredibly unique partnership between our vision of skiing and the color and light technology behind the Philips Ambilight TV.
Of course a few guys in videos do not on their own comprise a rebound effect. But come back in ten years and I bet you will see LEDs baked into everything from clothing to wallpaper to architecture in ways you couldn't begin to imagine, and they will be cumulatively sucking a lot of electricity.
